Music in New Super Mario Bros Wii - Problem

[StudioTeamTV]

I like the "Looping Audio Converter" and it works too but it usually has conflicts with the new super mario bros wii game because when I choose an audio file and do everything necessary I also choose the option "For files with no loop information" = "Ask for all files" then I click the button "Start" and it asks how I want to set the loop so I set it and when I'm in the game for example on the level selection screen in world one or two it works but when I select a level the music works for a while and then stops and it's grave silence (sound effects work but music doesn't)
so I need some advice if there's any way to do that.

btw: I want to simplify NSMBW to NSMBU so I use NSMBU sounds
NSMBU = New Super Mario Bros Wii U

I don't know how audio works in the NSMB games, but it sounds like there might be something the game's sound engine expects that the libraries I'm using just don't know how to put in there. I'm afraid there's not much I can do about that.
